A Cubic Boron Nitride (CBN) wheel is a type of grinding wheel made from a synthetic material known for its hardness and thermal stability. CBN is second only to diamond in terms of hardness, making it ideal for grinding hard materials like steel and carbide. These wheels are commonly used in industrial applications for precision machining and sharpening tools. CBN wheels are favored for their ability to maintain a sharp cutting edge and resist wear over time. They generate less heat during grinding, which helps preserve the integrity of the workpiece. Additionally, CBN wheels are often used in metalworking and automotive industries for efficient and effective grinding processes.
